All any of us can really comment on as far as beans go are the ones we or someone we know personally have grown, right? I have started probably about a dozen or so different strains from seed. To be honest, some of my favorites have been not the ones I purchased but the freebies that came with them. Here, in no particular order, are some strains I have started from seed and a quick comment on each.
White Widow
My first purchase ever, from AmsterdamMarijuanaSeeds a couple years ago. I have kept the strain going ever since. One of my patients asks for it all the time.
Caramelicious
Purchased same time as the WW. Very disappointed, mostly males. Not sure I ever got any usable bud.
Barney's Farm LSD
Purchased from Attitude.
Lots of phenos of this out there, apparently. The one I had grows these huge stringy buds. Takes forever. My first crop was extremely potent but it took at least 16 weeks and looked kinda weird. Subsequent crops (from clones) were dismal failures. Out of my rotation now.
Super Lemon Haze
Purchased from Attitude
One of my favorites. Great nose, great taste, excellent med. Good yield too. She's a keeper.
Kandy Kush
Freebie from Attitude
I grew a couple rotations of this. Good yield, great smoke. Got good feedback on it. I'm not sure I still have it around though.
Tangerine Dream
Purchased from Attitude
Rather disappointed with this one myself. I am not the only one. On the other hand, I have read reports from people who were very impressed with it. Takes a long long time to finish. Not a terrific yield. My pheno(s) didn't have that strong a taste or aroma and didn't really work that well as a med either.
Strawberry Diesel
Purchased from Attitude
Gets colorful at the right grow temps. Good producer, good med.
Afrodite
Freebie from Attitude
One of my favs. Grows a nice tall sativa with few side branches, like a cactus. Stalks get really beefy buds up and down the entire stalk. Potent aroma, great taste and very good med.
Pineapple Express
Freebie from Attitude
Keeper. Good yield of large dense bud. Skunky, good med.
That's most of 'em. Still got a bunch in the can.
I hear there should be seeds available at CannaMaineia.
